Tubbessing Attorney-Edward J. Norton [57] ABSTRACT A comprehensive mid-air collision prevention system incorporating three types of cooperating airborne stations of varying degrees of sophistication and cost to provide practically the maximum degree of safety for all types of aircraft from a small general aviation aircraft to an SST, while being substantially immune to false alarms and to saturation under dense traffic conditions. These last two features result from both the non-synchronous techniques employed and the use of one or more other discriminants employed.
